I recently had a conversation with a customer who was insistent that 50A DC flowing from the roof mount combiner box to the charge controller was dangerous. But, that isn’t at all the case when you consider the low voltage.

When our installation schedule permits, we occasionally take on small solar trouble shooting projects. This client came to us with an old solar charging system that wasn’t working properly (Not one of our jobs) and asked us what we could do to make it work. We remounted the solar panel, changed out his cabling and connected his charge controller. A system this size will maintain his batteries when the trailer isn’t in use.

This client needed a small solar charging system for DC loads and battery maintenance with a battery monitor to help them regulate energy consumption. What they got was a solar panel kit consisting of two of our SF100 solar panels connected in parallel with our roof mount combiner box. To reduce DC line losses, heavy 6ga wire was routed from the combiner box to the MPPT charge controller and then to the battery bank. Between the most negative battery and all negative connections, we installed a shunt to measure current. The shunt and the charge controller communicate with the Blue Sky IPN Pro monitor to give full system status with Amp-hour precision.
Solar Panel Kits for Boats
We don’t just do RVs. We have created a solar panel kit specifically for charging batteries on boats. This kit comes with a 50W solar panel, marine rated charge controller and wire harness. This is ideal for electric trolling motors, downriggers or simply maintaining the starter battery. The 50W solar panel will produce about 12 amp-hours per day in summer weather.

It is surprising that after being in the RV solar installation business for as long as we have that we still make regular discoveries regarding odd factoring wiring/components or cable routing challenges. Despite these obstacles we are still able to deliver. This client for example, with five 160W solar panels will now be able run a residential refrigerator and power an entertainment center. The Tri-Metric monitor will allow them to view battery status down to the amp-hour and the Bluetooth dongle will send solar charging system data to a smart phone.

With a 640W solar charging system, this client can now run a residential refrigerator, lights and some TV usage from energy captured by the solar panels. As a part of the system core that we regularly install, the client will also be able to monitor their battery bank and determine remaining charge to the Amp-hour.

We recommend four 160W solar panels when running a residential refrigerator, but sometimes you can get away with three if you aren’t running many other loads and you camp in sunny areas. With the Magnum hybrid inverter, this client can draw power from shore power and the battery bank at the same time. This makes a lot of sense when connected to a 15A source and you want to run large loads like air conditioners.

This client now enjoys the latest Bluetooth monitoring technology with their 800W solar charger and 640Ah AGM battery bank. Charging current, battery voltage, remaining battery capacity and battery temperature can all be read through the Victron Connect app on a smart phone.
2/15/2017 - 2016 Winnebago Sunstar LX27N, 27'
This class A motorhome got a 640W Solar charging system with a 440Ah AGM battery bank and a 2000W pure sine inverter. In addition to powering their refrigerator, our clients will now be able to run appliances like a microwave, a blender, a coffee maker, etc. without turning on the generator.

This client had a simple solar charging system installed. Because of the tight roof space, we used our compact SP100 solar panels. The addition of a single set of tilt bars allows for easy roof cleaning.
1/12/2017 - 2016 Airstream 26U, 26'
This Airsteam owner had one of our Essential Lithium battery banks installed with a battery monitor, 2000W inverter and 500W of roof mounted solar panels. Because lithium batteries are damaged when charged at temperatures below freezing, we included one of our cold charge automatic disconnect kits. Along with the roof mounted solar, we included a 120W Zamp folding panel on its own Victron MPPT charge controller.
2/10/2017 - 2016 Airstream Flying Cloud FB, 25'
This client came to us with an existing 400W solar charging system using flexible panels (which we discourage due to reliability issues) and an additional 120W folding panel. We replaced the original roof wiring because one of the four panels had stopped functioning, added two SP100 solar panels and upgraded the charge controller. We also replaced the PWM charge controller on the folding panel and added a Victron MPPT charge controller with Bluetooth monitoring. Next, we added a 600Ah Signature lithium battery bank and a 3000W inverter, which all fit tightly under the bed. This is one of our most elaborate installs.
2/6/2017 - 2013 Pleasure-Way, Mercedes Chassis, 22'
We installed a 220Ah AGM battery bank and a 300W solar charging system on this client’s van. In typical weather conditions, the solar panels will replenish about 75Ah per day (70% of the battery bank’s usable capacity). Solar, combined with alternator charging will keep these batteries topped off.
12/5/2016 - 2010 Creekside FQ, 20'
This trailer got a powerful roof mounted solar charging system along with a Zamp 120W folding panel. The folding panel has been customized to work on the same charge controller and monitoring system as the roof mount solar panels.
12/7/2016 - 2000 Chinook Premiere, 21'
This client wanted a simple solar charger for the flooded batteries on their Class B RV. We gave them a 200W MPPT charging system using our ultra efficient SP100 solar panels.

11/30/2016 - 2011 Airstream International, 28'
Our SP100 solar panels are ideal for the curved roofs on Airstream installations because of their compact footprint. This client ended up with a 300W solar charger and two new AGM batteries.
2/3/2017 - 2014 Newmar Canyon Star Road Hauler w/ 10' Garage, 36'
This client opted for a unique configuration with his lithium batteries and had us put them inside, under the couch. Wiring was extremely challenging but the installation was a success.
2/03/2017 - 2016 Monaco Diplomat, 44'
Four months prior these clients had us install four SF160 solar panels and a SunRunner Signature 40/2 Pro Core. On this installation they swapped out the Blue Sky components for Victron, added another 640W and got one of our 800Ah Signature lithium systems. Now they have 1280W of solar with one of the most advanced RV battery systems on the market.
2/2/2017 - 2002 Chinook Premiere, 21'
This client was tired of worrying about his batteries running low while using a CPAP machine. He also wanted to run a small refrigerator and power a laptop. He ended up with a roof covered in solar panels (460W), a 300Ah AGM battery bank and a silent Suresine 300W inverter.
